问题如下：
Gonzalez states that the investment strategy committee compiles data that may be needed to determine the Taylor rule for a particular country, including:
1) the real policy rate that would be targeted if growth is expected to be at trend and inflation on target,
2) the expected and target inflation rates, and
3) the expected and trend nominal and real GDP growth rates.
Which of the following information provided by Gonzalez is least likely required for a calculation of the Taylor rule?
选项：
A.Expected and target inflation rates
B.Expected and trend nominal GDP growth rates C.The real policy rate that would be targeted if growth is expected to be at trend and inflation on target解释：
Correct Answer: B
The formula for the Taylor rule requires the real policy rate that would be targeted if growth is expected to be at trend and inflation on target, the expected and target inflation rates, and the expected and trend real GDP growth rates. The expected and trend nominal GDP growth rates (choice B) are not explicitly part of the formula for the Taylor rule.
中文解析：
泰勒规则的公式要求在预期增长符合趋势且通胀符合目标时的实际政策利率、预期通胀率和目标通胀率，以及预期和趋势实际GDP增长率。预期和趋势名义GDP增长率(选项B)不是泰勒规则公式的明确组成部分。
答案的意思是，economic growth rate不等于GDP growth rate，所以least likely选的是B这样吗？
但是讲义中的注解直接使用的是GDP，是不是可以理解成，除非题目考economy growth rate的细节，其他情况下不用区分economy growth rate 和 GDP growth rate呢？
